For supporters of this idea, what is the downstream client tool that consumes the data prepared by the PI Integrator? Is the concern about disk space or how to only display data for a specified time range?

For the former, this seems to be a different type of “rolling” reporting use case that we do not currently have a solution for. In the mean time, as Rory mentioned below, a stored procedure on SQL would work if this idea is intended for SQL writers.

For the latter, is it possible to create “rolling timespans” for your graphs, reports, tables, etc.? For example, here’s a video on how to create calculated measures for a table based on last day or month of data: youtube.com/watch?v=NevFWL2JoMU
